Application mee April-7,-

,To @ZZ whom t may concer/n.

Be it known that I, Einw-14N P. y. a

citizen lof the United States,- residing at particularreference to adeviceof this charac ter for the purpose of displaying a portion of .tape which is being passed between the reels, which tape has prin-ted thereon words,

and their definitions such as foute-din ordinary dictionaries.

The principal object of this invention isto provide a simple device ofpthis character wherein a web is passedbeneath a window, which web moves at ahighspeed7 hilean index isjinterrnittently moved beneath-a ilar window, the intermittent movement g1-v ingtime for the eye to catch the letterseon# tained upon the index web.

Another object is to produce a device which is simple in construction .and therefore cheap to manufacture.

Aflinotl-rer Objectis to provide means where]-v bythe direction of rota-tion of the' web will automatically take place with a reversal df the turning element anda devicewhiuch will maintain a vsubstanti-ally uniform tension upon the web.

Other lobjects and advantages wi ll b e apparent during the course of the following description.

An intermediate gear`39 is interposed between the gears 27 and 29 and also carries a reduced gear 41 meshing with the gear 36.

Suitable bearings 42 serve to support the gears 28-34 and the gears 39-41- A suitable bearing 43 is secured to the casingv 5 and surrounds-the tubular portion 37.

By referring to Figure 4, it will be noted that the numeral 44 represents the end of the web being reeled and unreeled. web being made of relatively thin paper wouldiiot stand thev abrupt stopping when 'the end is reached. It is therefore cemented or otherwise secured to the end of a cloth piece 46, which cloth piece is in turn secured toa hinged member 47. This hinged member vis inturn hinged asatcS to the hub of ther drinn, it is of course understood that tins arrangement is the same on bothl drums.

An opening'is cut asshown at 49 in the hubof the drum so that the hinged member may assume the dotted line position, while the web is reeled thereon. rlihis hinged member is of sufficient length to abut the downturned end 13 of the guide plate 11, with the result that the motion of the drum is arrested.

By now referring to Figures 5 and 6, it will he noted that I have provided index spools 51 and 52. These index spools are supported upon suitable bearings secured to the casing 5 and are adapted to have an index web 53 passed therebetween. rllhis index web also passes over the guide plate 11. 1n order to rotate these indes7 spools l have provideda tooth wheel 54 which tooth wheel is `interposed between the end of the drums and each; of theindexspools. rlhese tooth wheelsare-'adapted to be'c'ontacted by a spring held `finger 56 pivoted as at 57 toa disc 58 secured upon one end of the drum. The arrangement is similar upon both drums with the exception thatl thespring pressed fingers are reversed as to'position. At 59 I have shown a spring member hav ing anenlarged end 61 "whichspring inember is adapted to lie against the ends ofthe tooth wheels for the purpose of preventing too rapid a rotation of the same and thereby maintaining a substantially uniform tension upon the index web.. rlthese spring fingers 59 are supported upon rods 62 se cured to the side of the' housing l5. l The operation of my device 'is'as folows:

This

Assuming that the device has been assembled or that it is desired to locate the word fee, the knob 38 is grasped and rotated, with the result that rotary motion is transmitted through the gear 36 to the gears 34 and 41, which motion is in turn transniitted through the gears 28 and 39 to which the gears 34 and 41 are secured, to the gears ,2G and 27 secured upon the shafts 21 and 22.

rlhe direction of rotation desired will determine the direction of movement of the web 44, as one of the clutches, for instance the clutch 17 will function to connect the shaft 22 to the spool 16. At the same time that this rotation of the spool 16 takes place, the spring finger 56 will contact one of the teeth of the tooth wheel 54, which will intermittently transmit movement to the iiidex wheel 52, with the result that as the web 44 travels rapidly past the window 7, the index web will travel in the same direction or at a slower speed and will be intermittently moved. As soon as the person has reached the point where the fee appears upon the index, the turning of the knob is stopped and then the knob 33 is grasped and slowly rotated, with the result that slow motion is then imparted from the gear 29 to the gears 26 and 27 through the intermediate gears 28 and 39. This slow motion enables the operator to slowly turn the web 44 when he has reached the approximate locality of the word he is searching for.

When the direction of rotation is re-4 versed, the clutch 17 will be released and the clutch 18 will take hold,`consequently, the device will operate in both directions with equal ease.

It will thus be seen that l have provided a very simple mechanism whereby two webs are fed past a window, one at a high speed and one at a lower intermediate speed, thus enabling a person to quickly find a given point upon the high speed web.

lt is to be understood that the form of my invention herewith shown and described is to be taken as a preferred example of the same, and that various changes in the shape, size and arrangement of parts may be resorted to without departing from the spirit of the invention or the scope of the subjoined claims.

Having thus described my invention, l claim 1. ln a device of the character described, a casing, a plurality of spools mounted with in said casing, two of said spools being adapted to reel and unreel a web therebetween, two other of said spools being adapted to reel and unreel a web therebetween, said first mentioned web being of greater width than said second mentioned web, means for rotating said webs simultaneously, one of said webs traveling at a high rate clutch mounted on each of said shafts, said` clutches being adapted to operate in reverse directions for the purpose of locking said spools to said shafts, a turning element interposed between said shafts, a gear secured to said turning element, a gear secured to each of said shafts, an intermediate gear mounted between each of said gears on said shafts and the gear on said turning element, a freely rotatable [rear mounted on said turning element and mehing with said intermediate gears, means for turning said freely rotatable gear, a second set of spools mounted in said casing, aweb extending between said second mentioned spools, a web extending between said first mentioned spools and means for imparting intermittent movement to said first mentioned web, while said second men- 3.
